PTFE film is a material made of polytetrafluoroethylene resin coated on ultra-fine glass fiber fabric. This film has good welding performance, excellent anti-ultraviolet, anti-aging performance and flame retardant properties. In addition, its anti-fouling self-cleaning is the best of all building membrane materials, but its flexibility is poor, the construction is difficult, and the cost is also very alarming. The processing method is to quickly put the glass fiber fabric into the Teflon melt many times, so that the fabric has a uniform Teflon coating on both sides, so that the permanent PTFE film was officially born.

Since then, permanent membrane structure has been popular in the United States, and many scholars have conducted in-depth research on membrane structure. The follow-up test results after 20 years show that the mechanical properties and chemical stability indexes of this membrane material have only decreased by 20% ~ 30%, and the color has hardly changed. The surface layer of the membrane is smooth and elastic. Dust and chemical particles in the atmosphere are extremely difficult to adhere and penetrate. The original clean surface layer and light transmittance can be restored by rainwater washing the building membrane, which is sufficient to show the strong vitality and broad market prospect of PTFE membrane.

Features of PTFE film:

1. PTFE film has the advantages of high strength, good durability, fire retardant, good self-cleaning, not affected by ultraviolet rays and light weight (about 1/30 of the weight of the previous steel ceiling). It can be installed on site after cutting and fusing in the factory in advance, which can shorten the construction period.

2. PTFE film has high reflectivity and low absorption rate of sunlight, which can inhibit the penetration of solar energy into structural buildings by the minimum heat capacity. At the same time, because of its translucent characteristics, it is not compared to the use of artificial lighting during the day, which can substantially save energy costs.

3, PTFE film structure buildings generally do not need internal support to be able to cover the vast space with film, can be free to design, use of the diversity of space.

4. The light transmittance of PTFE film is about 13%, and it can convert sunlight into moisturizing and diffusing light with less shadow, which can obtain the original color of the same object as outdoor.

5. PTFE has the incomparable high self-cleaning property of PVDF. Fluorine resin has the functions of non-adhesion, waterproof, etc. The dust and atmospheric dirt accumulated on the surface are cleaned after being washed by rain, and are kept clean and white for a long time.
